Figure 7

Schematic illustration of four possible mechanisms of temporal correlation in the twinning induced AE time series (a) the twin-dislocation interaction, (b) the relay-like mechanism whereby the lenticular twin terminating at the grain boundary promotes initiation of a new twin in the neighbouring grain, (c) concurrent propagation of several closely spaced twins in the same grain and (d) self-correlated propagation of the twin lamella. Consecutive snapshots obtained from in situ high-speed video recording of twinning related processes in Mg are shown on the right-hand side in support of the proposed mechanisms.
